2. What data we collect

We collect minimal data. Specifically:

• Analytics data (with your consent): We use Google Analytics 4 to understand how visitors use the site. This collects anonymised data including pages visited, time on site, device type, browser type, approximate geographic location (country/city level), and interactions with the calculator (e.g. which features are used). Google Analytics may assign a random client identifier stored in a cookie.
• Affiliate link clicks: When you click an affiliate link to an investment platform, we record the platform name as an analytics event. We do not record any personal information about you in connection with this click.

We do not collect:

• Your name, email address, or any contact details
• Financial information or calculator inputs (these are processed in your browser only)
• Payment or banking information

3. Legal basis for processing

Under UK GDPR, we process data on the following bases:

• Consent (Article 6(1)(a)): Analytics cookies are only set after you give consent via our cookie banner. You can withdraw consent at any time by clearing your cookies or changing your cookie preferences.
• Legitimate interest (Article 6(1)(f)): We use essential site functionality (such as URL state parameters for calculator settings) to provide the service you are using. No cookies are required for this.

4. Cookies

We only set cookies if you accept them via our cookie consent banner. For full details of the cookies used, their purposes, and durations, please see our Cookie Policy.

If you reject cookies, no analytics cookies are set and Google Analytics does not load.

5. Third parties

We do not sell your data to any third party. We do not use advertising tracking pixels or retargeting tools.

6. Affiliate links

This site contains affiliate links to investment platforms. When you click these links and sign up, we may earn a commission at no extra cost to you. Affiliate partners may set their own cookies on their own domains when you visit their sites — please refer to their respective privacy policies for details.

7. Data retention

Google Analytics data is retained for 14 months, after which it is automatically deleted. We do not maintain any separate database of user data.
